problem with acceleration((( (is 220d, 2010)

[World_Man]

Good people please help! I bought a car not long ago. The problem is not constant and does not occur often, although recently more and more often. Sometimes from 2 gears with sharp acceleration And it is power and rarely this occurs in 3 gears. I changed the fuel filter and metal shavings were very dirty at the bottom of the filter housing. I understand this is all very sad.

The problem is that if the power drops sharply, the car goes jerkily. It feels like there is not enough boost. Although the rest of the engine runs smoothly on cold and hot, oil does not eat.

The acceleration is more savage in 1st and 2nd gear so jerkiness is more pronounced. 

I doubt it's a turbo problem but it could be a clogged up egr valve or dirty dpf. 

Have you cleaned the MAF sensor an easy job that's relates to what you have stated as well.
